Security readout for executives and security teams
Plain-English summary
CVE-2016-7151 is a crash bug in Capstone 3.0.4, a disassembly library. A malformed x86 instruction path can trigger an out-of-bounds read and segmentation fault. Business impact is mainly availability risk where Capstone processes untrusted or automated inputs.
Executive priority
Treat as a targeted availability risk for systems that rely on automated binary analysis. Prioritize patching if Capstone handles untrusted submissions or runs in production workflows.
Technical view
The CVE describes an out-of-bounds read causing SEGV in X86_insn_reg_intel within arch/X86/X86Mapping.c in Capstone 3.0.4. Public references are a GitHub pull request and commit. The bundle does not provide CVSS, CWE, or affected CPE metadata.
Likely exposure
Exposure is most likely in applications or services embedding Capstone 3.0.4 and disassembling x86 content from untrusted, user-supplied, or large automated sources. Evidence for broader affected versions is not provided.
Exploitation context
The source bundle does not show CISA KEV listing or active exploitation. Public GitHub references indicate the issue and code change were visible, but no exploit status is established by the provided sources.
Researcher notes
Metadata is sparse: no CVSS, CWE, CPE, or named fixed release is provided. Analysis should stay scoped to Capstone 3.0.4 and the referenced X86Mapping.c fix unless vendor records add details.
Mitigation direction
- Identify whether Capstone 3.0.4 is present directly or as a bundled dependency.
- Apply the vendor fix or upgrade to a release containing commit 87a25bb543c8.
- Restrict untrusted binary analysis inputs until patched where feasible.
- Monitor Capstone project guidance for affected-version and release details.
Validation and detection
- Inventory binaries, packages, and vendored source for Capstone 3.0.4.
- Confirm whether arch/X86/X86Mapping.c includes the referenced fix.
- Review services that disassemble user-controlled x86 input.
- Check crash logs for SEGVs in X86_insn_reg_intel.
